“…A distinct improvement of the detection limit of brominated and iodinated compounds by a factor of 6 and 80, respectively, are observed for ICP-MS compared with MIP-AED. The MIP-AED detection limits listed in Table 3 are in good agreement with other literature values [23,24]. The range of wavelengths, which can be covered by the diode-array system of the AED, is about 40 nm.…”

Inductively coupled plasma-mass spectrometry (ICP-MS) was coupled to a gas chromatographic (GC) system with electron capture detector (ECD), which enables relatively easy characterization and quantification of brominated and iodinated (halogenated) volatile organic compounds (HVOCs) in aquatic and air samples. The GC-ECD system is connected in series with an ICP-MS by a directly heated transfer line and an outlet port-hole for elimination of the ECD make-up gas during ignition of the plasma. The hyphenated GC-ECD/ICP-MS system provides high selectivity and sensitivity for monitoring individual HVOCs under fast chromatographic conditions. The ECD is most sensitive for the detection of chlorinated and brominated but the ICP-MS for iodinated compounds. The greatest advantage of the use of an ICP-MS is its element-specific detection, which allows clear identification of compounds in most cases. The absolute detection limits for ICP-MS are 0.5 pg for iodinated, 10 pg for brominated, and 50 pg for chlorinated HVOCs with the additional advantage that calibration is almost independent on different compounds of the same halogen. In contrast to that detection limits for ECD vary for the different halogenated compounds and lie in the range of 0.03-11 pg. The two-dimensional GC-ECD/ICP-MS instrumentation is compared with electron impact mass spectrometry (EI-MS) and microwave induced plasma atomic emission detection (MIP-AED). Even if EI-MS has additional power in identifying unknown peaks by its scan mode, the detection limits are much higher compared with GC-ECD/ICP-MS, whereas the selective ion monitoring mode (SIM) reaches similar detection limits. The MIP-AED detection limits are at the same level as EI-MS in the scan mode.

“…Triclosan (5-chloro-2-(2,4-dichlorophenoxy)phenol), as a widely used chemical for antimicrobial and antifungal activities, has been identified as a contaminant in rivers and lakes (Latch et al 2003;Singer et al 2002;Tixier et al 2002;Lindström et al 2002;Adolfsson-Erici et al 2002;Kolpin et al 2002;van Stee et al 1999;Okumura and Nishikawa 1996). It has been applied to a variety of personal care products including toothpastes and mouthwashes.…”

A gas chromatography-mass spectrometry (GC-MS) method was developed for the identification and quantification of 2,8-dichlorodibenzo-p-dioxin (2,8-DCDD) in toothpaste and mouthwash consumer products. Liquid-liquid extraction and solid-phase extraction were used in the sample preparation. The limit of detection was 0.96 ng/g in toothpaste and 0.83 ng/g in mouthwash. The accuracy represented by relative errors was less than 12.5%. The intra-day and inter-day precision, which are represented by the relative standard deviation values, were within 11.2 and 10.6%, respectively. The method was successfully applied to analyze 2,8-DCDD in toothpaste and mouthwash products, as well as that from the photo-degradation of triclosan spiked in both sample matrix.
